A second study in a driving simulator found that people in larger drivers' seats were more likely to "hit-and-run" when encouraged to drive quickly.

Drivers of real cars in New York were also more likely to be found illegally parked if they had larger seats, researchers reported in the Psychological Science journal.

Andy Yap, a PhD student at Columbia Business School in New York, who led the study, explained: "In everyday working and living environments, our body postures are incidentally expanded and contracted by our surroundings — by the seats in our cars, the furniture in and around workspaces, even the hallways in our offices – and these environments directly influence the propensity of dishonest behaviour in our everyday lives."
